J'ai parlé trop vite :

Hyper-threading
Hyper-threading, an innovation from Intel, is a major hardware
enhancement supported by the 2.6 kernel. Basically, hyper-threading can
create multiple virtual processors based on a single physical processor
using simultaneous multi-threading technology (SMT); multiple
application threads can be run simultaneously on one processor. To take
full advantage of it, applications need to be multithreaded.

Il semblerait donc qu'il faille utiliser un kernel SMP.
